Synopsis

Keywords: Blood Vessels, Flow

Motivation: While carotid artery stenting is well-documented as safe and effective, its impact on blood flow dynamics and functional correlates remains underexplored.



Goal(s): To investigate changes in internal carotid artery blood flow associated with carotid artery stenting.






Approach: Fourteen participants underwent flow MRI at baseline, 2 months, and 4 months, post-stenting. Internal carotid artery flows were calculated and compared between baseline and 2 month follow-up.



Results: Results indicate CAS significantly reduces flow lateralization, with changes to both ipsilateral and contralateral flows. Total internal carotid flow increased in roughly half of the patients, while the rest showed minor decreases.



Impact: Our findings suggest carotid artery stenting maintains or increases overall carotid blood flow, potentially benefiting functional recovery.
